### Testing Best Practices

- Minimize `Thread.sleep()` - use only when absolutely necessary
- For timestamp tests: use minimal delays (50-100ms)
- Clean only test-specific indices (not `_all` unless needed)
- Use `runner.refresh()` after index operations
- Test with realistic multilingual content

### Key Test Classes

        @DisplayName("Should handle very long messages")
        void testVeryLongMessage() {
            StringBuilder longMessage = new StringBuilder();
            for (int i = 0; i < 10000; i++) {
                longMessage.append("x");
            }
            String message = longMessage.toString();

            TransportException exception = new TransportException(message);
